BACKGROUND OF THE INVENTION

The present invention comprises a new a distinct cultivar of chrysanthemum plant that is a natural occurring sport of a parent chrysanthemum named Refocus. Parent chrysanthemum Refocus is also described in this application. The new cultivar was discovered as a whole plant mutation in May, 1993 by Rob Noodelijk in a greenhouse in Ter Aar, Holland.

The first act of asexual reproduction of Red Refocus was accomplished when vegetative cuttings were taken from the initial selection in August 1993 in a controlled environment in Ter Aar, Holland.

SUMMARY OF THE INVENTION

The present invention is a new and distinct variety of chrysanthemum bearing small sized blooms with red ray florets and green-yellow disc florets.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.

FIG. 1 shows the stem of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom and foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

This new variety of chrysanthemum is of the botanical classification Dendranthema grandiflora. When grown in the vicinity of Ter Aar, Holland, it has a response time of approximately 8 weeks. This new variety produces small sized blooms with red ray florets and green-yellow disc florets having a 3 week performance (i.e., vase life of 21 days). This new variety of chrysanthemum has been found to retain its distinctive characteristics throughout successive propagations. However, the phenotype may vary significantly with variations in environment such as light intensity and temperature. To show the phenotype as described Red Refocus may be planted year round under greenhouse conditions in Holland.

The following is a description of the plant and characteristics that distinguish Red Refocus as a new and distinct variety. The color designations are taken from the plant itself. Accordingly, any discrepancies between the color designations and the colors depicted in the photographs are due to photographic tolerances.
